Get json data from a htttp based web service C# -

i can't recieve json data http web service, because of data size - guess - 7 mb, first tried :

private async task<string> getresponse(string url) {     httpresponsemessage response = null;     httpclient client = new httpclient();     try     {         response = await client.getasync(url);     }     catch (exception )     {         throw;     }     return await response.content.readasstringasync(); } 

but gives me "task canceled exception", after doing search , found might request timeout limit probleme, implemented second solution setting timeout limit 2 minutes :

httpclient client = new httpclient(); client.timeout = new timespan(0, 2, 0); 

when executing, there no result, no exception , app blocks @ method

client.getasync(url);
